On Jan. 19, stand-up duo The Puterbaugh Sisterz performed in the weekly comedy showcase (that they also host) "Entertaining Julia" at Town Hall Pub. In their particularly musical set, they ennact every burlesque act ever and wax nostalgic about "Barbie and The Rockers." The Tribune has the exclusive video. "Entertaining Julia" plays Town Hall Pub, 3340 N. Halsted St., every Sunday at 9:30 P.M.
